什么情況下才使用salt-ssh，有一些比較老的紅帽服務器，也有一些不方便安裝salt-minion客戶端。總會有一些服務器比較難安裝上salt-minion的。

好了，下面來說說簡單配置

默認使用roster配置文件

vim /etc/salt/roster?

#?Sample?salt-ssh?config?file #web1: #??host:?192.168.42.1?#?The?IP?addr?or?DNS?hostname #??user:?fred?????????#?Remote?executions?will?be?executed?as?user?fred #??passwd:?foobarbaz??#?The?password?to?use?for?login,?if?omitted,?keys?are?used #??sudo:?True?????????#?Whether?to?sudo?to?root,?not?enabled?by?default #web2: #??host:?192.168.42.2 hdd:??????????????????????????????//ID名字可以隨便定義host:?10.0.0.221user:?hddpasswd:?66666sudo:?Ture

已經完成配置！下面直接使用salt-ssh

第一次運行沒有添加-i，未能如期運行。

root@salt-master?~]#?salt-ssh?"*"?-r?'free?-m' hdd:----------retcode:254stderr:stdout:The?host?key?needs?to?be?accepted,?to?auto?accept?run?salt-ssh?with?the?-i?flag:The?authenticity?of?host?'10.0.0.221?(10.0.0.221)'?can't?be?established.ECDSA?key?fingerprint?is?b9:36:f5:d8:3a:88:94:93:43:78:8e:cb:43:78:8e:cb.Are?you?sure?you?want?to?continue?connecting?(yes/no)?? [root@salt-master?~]#

添加-i參數繼續執行命令

[root@salt-master?~]#?salt-ssh?"*"?-r?'free?-m'?-i hdd:----------retcode:0stderr:Warning:?Permanently?added?'10.0.0.221'?(ECDSA)?to?the?list?of?known?hosts.stdout:hdd@10.0.0.221's?password:?total???????used???????free?????shared????buffers?????cachedMem:??????????7856???????6698???????1157?????????18????????317???????4298-/+?buffers/cache:???????2082???????5773Swap:?????????8061??????????0???????8061 [root@salt-master?~]#?

但是我有一個問題，保存的密鑰放在哪里呢？暫時我未有發現。
